To all-whomii may concern: is a section on the line 2-2 of Fig. 1, look-Be it known that we, James N. Jormson and JOHN H. JOHNSON, citizens ofthe United States of America, and residents of Flomaton, in the countyof-Escambia and State of Alabama, have invented certainnew and usefulImprovements i'n-Motor-Wheels, ofwhich the following is a specification.

This invention relates to certain newland useful improvements in motorwheels of that.

class in which the" wheel is mountedtorevolve on anon-revoluole'hollow'shaft and 'arranged to take steam through thecenter of-the wheel upon one side and toexhaust it axially upon theopposite side. 7 The present invention has for its objects among othersto provide asimple and inexpensiwgsnotor wheel adapted to'be driven yany expansive fluid under pressure, being readily reversible and capableof embodiment as either a single or a compound motor.

We aim further at improvements'in the details of construction wherebychea ness of manufacture is assured,with capability of boiler or anyother'suitable source of motive ready assemblage and adjustmentofthepartsas well as-surety or motive fluid.

Other objects and advantages of the-invention wi]l-' hereinafter appearand the novel features thereof will be articularly pointed out in theappended claims.

The present inventionis capable of embodiment in various forms and inthe resent instance we have shownthose whic .we' at the presenttimeconsider preferable. It is to be understood, however, that theinvention is not to be restricted to such forms,

nor to the details of construction, proportion of parts, etc., as thgsame is subject to variations, modifications'and changes withoutdeparting from the s irit of the invention or sacrificing any 0 itsadvantages. We, therefore, reserve the right to make such changes,variations and modifications as come properly within the scope of theprotection prayed. The invention as embodied in such preferred forms isclearly illustrated in the accompanying drawings, which, -with thehumerals of reference marked thereon, form a partof this specification,and in which Figure 1 a substantially central sec- Fig. 2.

Like numerals of. reference indicate like parts ,throughout ',the=different views.

In practice thejz'wheel may'be supported in any-preferred way, forinstance, it may be-mounted upon a pipe 1, as shown in Fig. 1, which may-be" a"-.-.pipe connected -with and de'signed'to receive steam" from asteam fluid. It is'evident,'-however, that it may be suitable base .orsupport when be at- .tached to or form a part "of any suitable fixedmeans whereby-the wheeilmajbesupported in thedesiredpositioiif-ivitiijrclation to the other parts. *Th'ef ljiiaiinefiof sup porting, however,- is one thatinay be varied and changed to suitthe circumstances and,

therefore, the invention in its other respects is in no wise restrictedto this or, any-other particular means o'f mounting of the wheeL In thepresent instance, the wheel in its most'simplified form comprises acasing 2 having a detachable head 3 secured in place by screws or anyother suitable means 4,

which head, in this instance, is shown as provided with an extensionorni'pple 5 for connection with the exhaust-pipe 6 which, as will beevident,- may be revolublymounted upon said nipple or extension 5, sothat it may be. turned-up 'or down or 'in any other desired direction.hth 7 2 as"eextensi' mu n which is fast a belt ulle 8. Within ilietubular extension 7 is disposed. a hollow shaft 9 which isscrew-threaded at one end,

as seen at 10, and is screwed into the nipple radially and extendinginward a greater 'or less distance from the said flange. These vanes arearranged at op siteedges' of the posed at a right angle to by means ofwhich the throttle may be re 11 of the T 12 int0 which the pipe-1 is secured. This pipe 1 is provided with a suitable valve 13 whereby thecontrol of the motive fluid may beregulated or shutoff when desired. I

141s a block or the like upon the hollow shaft, retained in position byascrew or the like 15 and carrying an oil cup 16 from which oil isconducted to the inclined passage 17 to the bearing 7.

The casing 2'has the peripheral flan e 18 into which the screws 4 areengag' as seen best in Fig.' 1, and upon the inner face of this casingare thevanes 19 arrangedflange, 'as seen clearly;- in ig. 1.

Theinner 3 end of the hollow .shaft 9 is rovided with an enlargement 20,as seen in igs. 1,.2and-3, and from the bo'reofthis shaft extendin-opposi-te directions passages 21- and 22 which communicate with thefeedpipes 23 and 2t respectively. These pipes may be integral with orsecured to the hollow shaft in any suitable manner and, as seen in Fi s.2 and 3, these feed pipes extend both in the same direction practicallyoutward from the enlargement 20, each taking a substant-iallyright-angled bend fromthe passages 21 and 22, their free ends. extendingin close proximity to the inner periphery of the casing and provided.with outlets 25 and 26 respectively which are .disei'rJength andarranged to discharge in opposite directions.

These feed pipes are designed to revolve between the vanes, as will beevident from Figs. 1 and 2.

27 is the throttle valve; It is exteriorly threaded, as seen at 28, toengage the threaded portion 29 of the T 12. as seen in F 1g. 1. It isrotatable within the" hollow shaft ,9 in order to control the flow of motive fluid to the interior of the wheel from the pi e 1. It is providedwith two ports 30 an 31 diametrically disposed to each other, as seen inFig. 1, at the outer end, and at the inner end it provided with a port32, as seen clearly in Figs. 1, 2nd 3. This port 32 is in alinement withthe ports or passages 21 or 22 of the enlargement 20 of the hollowshaft, as seen in sa d 1, 2 and 3, and designed to discharge the motivefluid through said valve into one or the other of the pipes 23 or 24,dependent upon the osition of the throttle valve.

e throttle valve has an extension 33. rigid with which, is the operatinglever 34 volved in its bearing. Pivotally mounted on th s-extension 33,as at 35,.is a lever 36 i between the free end of which and the lever 1suitable manner and receiving1 fluid through the pipe 1, with t 1 34 isa sprixig 3'i, the other end of the lever 36 being bent at an angle andits extreme end 38 forming a pawl or the like adapted to engage in oneor the other of the open- The mode of operation will be readily un}derstood from the foregoing description when taken in connection withthe annexed ings 39in the guter end of the-portion 29 drawings, and,briefly stated, is as follows:

The hollow shaft 9 being supported in any the motive e throttle in theposition in which it is seen in Fig. 1, the

lluid-enteri ng through the pipe 1.takes the course indicated by 'thearrows, passmgl through the port- 31' and along. the hollow throttle,out through the passage 21 and through the feed pipe 23 and out itspassage 25, the motive fluid actiti; as follows; The wheel becomes fullof cad steam, the'live steam rushing in drives the dead steam againstthe rim of the wheel, compressing it by forcingit through between thevanes and the walls of the wheel all at the sometime and graduallypushing the-dead steam out at theexhaust. The vanes do not retard theflow of the motive .fluid in running as the vixnes run by the steam ormotive fluid instead of throu h the same as heretofore; By this form orconstruct-ion, we obtain great s d and power under less pressure and t ewheel runs smooth and p'racticall noiseless. By dis engaging the end'38o the pawl 36 from its notch in the member 29 and giving the port 32into the throttle valve a. half revolution until theport 32 at the innerend of the throttle valve is brought into its downward position so as tobe thrown into communication with the passage 22, the motive fluidentering the throttle valve through the pipe 1 passes through thethrottle valve and out into thepassage 22, as indicated by the arrow inFig. 3, and thence along the feed pipe 24 and out the exit'passage 26,thus turning the wheel in the opposite direction. When it is desired toshut oil the flow to the wheel, the throttle valve may be turned into aposition intermediate the two positions seen 1n Figs.

2 and 3 respectively when there is no es- .cape for the fluid-from thethrottle valve into either of the passages 21 or 22.

In Fig. 6 we have shown a slightly modified form in which the two feedpipes 40 and 41 extend 'in diametrically opposite directi ns from thehollow shaft with their outer ends arranged incloseg: proximity. to theinner periphery of 'fl'ange 18 and provided withthe outlet ports 42 and43 extending in opposite directions; The mode of operation'issubstantially the'mme as in the form just before described and shown in.Figs. 1, 2 and 3. Figs. 7 and .8 we have shown afurther modification.in which thevanes-are dis pensed with and the feed pipes 44 and--45extend insubstantially diametrically oppo'-- site directions and havetheir 'ends curved, as seen at 46, the free ends extending oppositedirections withtheir outlets i7-.i-and 48extending soas to deliver themotive iiuid'in opposite directions withinthe'cas ra throttle isReversal of the 20.
